Quality attributes for six mAbs (mAb-A to mAb-F) between RCB, Tox, and FIH stages. RCB was at 5 L scale with individual 6 clones (RCBs), Tox was at 200 L scale with a pool of 6 clones (RCBs), and FIH was at 1,000 L scale with the lead clone. (a) Charge variants: acidic variants, main, and basic variants; (b) HMW and Monomer; (c) Major N-linked glycans: G1F, G2F, and Man5. RCB: Research Cell Bank; FIH: First-in-Human; HMW: High molecular weight. For RCB, error bars represent the spread of all 6 clones (n = 6). For FIH, error bars represent one standard deviation of multiple batches (n = 3–6).
